I've just tagged skiboot-5.0.4 and put up a pull request for this to go
into the upcoming op-build v1.4.
There's a few changes here that are worth noting, including some
important bug fixes:
- cpu: fix hang in opal_reinit_cpus()
A bug introduced in 87690bd19dbb (skiboot-5.0) mean that if a host OS
was calling opal_reinit_cpus() with offline threads (e.g. kdump with
SMT!=8 on POWER8), we could, instead of kdumping, hang forever.
A side effect of this fix is that it is not possible to have a kdump
kernel be a different endian than the host kernel.
- Correctly set the Relative Priority Register
This means that on boot, the RPR will be set to a known value (the
same as phyp). This register controls the relative priority of each
thread in a core.
Previously, we were leaving it to whatever HostBoot set it to, which
may not be the desired value.
- enable prd_init() for Firestone platform
- fix bug in hw/bt.c that would dereference an invalid address, likely
causing a checkstop.
- ipmi/sel: fix use after free
